1.2 SAFETY PRECAUTIONS
DANGER!!!
The following instructions are essential safety measures that you must take.
Unless observed, improper way of use leads to death or serious injury of yourselves or others.
[1] Know your machine. Read carefully this manual and also a manual of the Drill Stand to be used with this Drill Motor in
order to learn the application of the machine and the limitations as well as potential hazards associated with the machine.
[2] During the operation, the Core-Bit rotates with very high speed. Do not wear loose clothing, dangling objects, rings, and
jewelry to eliminate the risk in which the operator gets caught in the moving parts such as the Core-Bit. Keep your face
away from the air inlet, outlet of the motor. Long hair must be tied up.
[3] Always wear protective clothing such as helmets, safety goggles, earplugs, heavy-duty gloves, and special work boots
with reinforced toe. (During the operation, do not wear gloves to reduce the risk in which the operator gets caught with the
Core-Bit.)
CAUTION!
This machine generates sound pressure level of 84 dB(A). Always wear ear protection when working with this
machine.
[4] Do not operate when you are tired or under the influence of any medicine, drugs, and alcoholic beverages.
[5] Consider the work area environment. Do not expose the drill motor to water. Water in the drill motor increases the risk of
electric shock.
[6] Do not operate the machine in the presence of flammable liquids or explosive or combustible gas. Sparks generated by
Armature and Carbon Brushes in the Drill Motor could cause an explosion of fire.
[7] In case of operation in a closed room or basement, make sure that the air is in good condition (plenty of oxygen, no toxic
gas), before operation.
[8] Before operation, do ensure that the Core-Bit is connected with the Spindle of the Drill Motor tightly and securely, so that
the Core-Bit will not come off and not cause damage to persons and property around.
[9] Before operation, do ensure that the Drill Stand is fixed firmly to the surface of drilling object, when using drill stand.
[10] Never use this machine without the Portable Residual Current Device (PRCD), which is equipped in the electric cable.
And inspect it periodically to confirm that it works properly.
[11] Before starting drilling, make sure that there is no live electric cable in the drilling object that the Core-Bit will cut through.
[12] Do not allow other persons to use this machine, unless they have read and understand this manual.
[13] Unintentional start of the Drill Motor is quite dangerous. When the Drill Motor is not in use with the drilling operation, do
ensure that the plug is disconnected from the power source outlet.
[14] If the main power supply gets power failure during operation, turn off the switch immediately in order to avoid the
unintentional start of the Drill Motor.
4
[15] Protective function of this machine may not work properly when atmosphere temperature is below 0℃ （32°F）or above
40℃ （104°F）. After using in cold temperature, drain out the all the cooling water to avoid possible damage of seals.
SAFETY
[16] When drilling at high level, keep proper footings and balance at all times. Prepare yourself for the kick back, which may
occur when a Core bit gets stuck. Maintain a firm grip, in order not to drop the machine, too. Use extra care when you are
on ladders, roofs, scaffolds, …etc.
[17] When drilling through floors, the core will be likely to fall down from inside of the Core-Bit. Under these circumstances,
provide proper protections for people and property below the coring area. For example, fencing around the particular area
down floor, making the place “KEEP OFF” …etc.
[18] Never yank the cord to disconnect it from the socket. Keep the cord away from heat, oil and sharp edges.
[19] Plug is essential for safety. Never connect directly to distribution board without using a plug for fixed installation.
[20] This machine must not be used for drilling upwards for electrical reasons. When drilling horizontally on the wall, use of
water collection device is highly recommended.
[21] All the services, with the exception of maintenance written in this manual, must be carried out by authorized service center.
[22] Always compare the voltage value on your Core Drill with your proper supply source. The power supply source should not
vary more than 10% from the voltage figure shown on the decal on the drill motor..
[23] Do not operate the machine alone. Make sure you can contact someone in the event of accident.
[24] Do not allow anyone near the machine when starting or operating. Keep bystanders, children, and visitors away from the
machine and cable.
[25] Use common sense and plan your work to avoid injuries. Your own safety as well as the safety of your fellow worker
depends on your carefulness and good judgment during the operation.
[26] Avoid body contact with earthed or grounded surfaces (e.g. pipes, radiators, ranges, refrigerators).
[27] The use of any accessory or attachment other than one recommended in this instruction manual may present a risk of
personal injury.

1.3 IMPORTANT OPERATING INSTRUCTIONS
WARNING!!
Following instructions are essential measures that the operators must take.
[1] Ensure that the adequate water is supplied to the Core-Bit during operation, unless Dry-Bit is used. Do not allow
excessive heat to be generated at segments of the Core-Bit. The overheat may result in breakage of the segments, and
may lead to injury of the operator.
[2] Do not block the cooling air inlets of the Drill Motor. If the inlets are blocked, the cooling might be insufficient and the Drill
Motor could burn.
[3] Do not let water get into the Drill Motor. The water in the motor can decrease the insulation capacity and the Drill Motor
could burn out. Also, do not expose the Drill Motor to rain or snow.
[4] Do not push the Core-Bit too hard. Too much pressure on the Core-Bit will decrease the drilling capacity and might burn
the Drill Motor.
[5] When using with Drill Stand, make sure the Carriage Block (Feed House) is properly adjusted and that the tool is in line
with the Drill Stand, before start drilling. When you adjust it, make sure the plug is disconnected from the main power
source.
[6] Check for damaged parts. Inspect guards and other parts before use. Check for misalignment, binding of moving parts,
improper mounting, broken parts, and any other conditions that may affect operation. If abnormal noise or vibration
occurs, turn off the machine immediately and have the problem corrected before further use. Do not use a damaged
machine as it is. Tag damaged machine “DO NOT USE” until repaired or replaced by an authorized service center unless
otherwise indicated in this manual.
[7] Maintain tools carefully. Keep handle and grip dry, clean, and free from oil and grease. Keep cutting edges sharp and
clean. Follow instructions for lubricating and changing accessories. Periodically inspect the machine’s cord for damage.
Have damaged parts repaired or replaced by authorized service center. If the switch does not turn on it on and off, do not
use the tool. Have defective switches replaced by an authorized service center.
[8] When the tool is used outdoors, use only extension cord intended use for outdoors use and so marked.
[9] When not in use, store the machine in a dry secured place. Keep out of reach of children.

UNPACKING
3.0 UNPACKING
After unpacked, in the first place, be sure to check for any damage of the drill motor. And then check the contents of
tool bag.
GROUNDING INSTRUCTION
4.0 GROUNDING INSTRUCTION
This machine must be connected to a properly grounded outlet. If the tool should electrically malfunction or
breakdown, grounding provides a low resistance path to carry electricity away from the operator, reducing the risk of an
electric shock.
PORTABLE RESIDUAL CURRENT DEVICE (PRCD)
5.0 PORTABLE RESIDUAL CURRENT DEVICE (PRCD)
According to the European standards EN61029-1 and IEC 1029-2-6, the electrical connection of diamond core drills
with water supply must be operated via a residual current device (RCD or PRCD).
DANGER!!!
Note that you have a potential hazard that the drill may cut a live electric cable hidden in the drilling
object. To reduce shock hazard, use Residual Current Device (RCD), or Ground Fault Circuit Interrupter
(GFCI), or Insulation Transformer. Connection to main power supply must be made using one of these
devices.
RH1531 is equipped with an inline PRCD in between the cable. It cuts off the main power supply to drill motor if it
found an electric leakage, which exceeds 30mA. When it cuts off the main power supply, stop using the drill, do
not touch grounded surface. Have qualified electrician check the job site and the drill. If need, send the drill for
repair.
CAUTION!
Warranty may not be applied for any damage that is found after start using this equipment. It would be
considered to be made by hit.
W
ARNING!!
Improper connection of the grounding wire can result in the risk of an electric shock.
Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not
modify the plug provided with the machine. If the cord or plug is damaged, have it repaired by a Shibuya’s
authorized service center, before use. If the plug will not fit the outlet, have a proper outlet installed by a
qualified electrician.

FEATURE OF THIS MACHINE
6.0 FEATURE OF THIS MACHINE
[1] OVERLOAD SWITCH AND CIRCUIT PROTECTOR (SWITCH)
This machine is equipped with a Circuit Protector and an overload switch to reduce the risk of damage of the Drill
Motor. The Circuit Protector trips when the Drill Motor is overloaded. Too much feeding pressure will cause the Circuit
Protector and overload switch to trip frequently. And frequent trip may lead to damage on the Drill Motor. Try to operate
so as not to make the Circuit Protector trip. When overload switch tripped the black button near the grip handle will pop
up. When circuit protector trips at rig-mounted mode, it will turn off the main switch. These devices are not reset until it
gets cool. If the overload switch does not stay in or if the main switch does not kept at ON position, wait a few minutes
and try again.
CAUTION!
Do not fit any Circuit Protector or Overload Switch of wrong specification that may cause damage of the
Drill Motor. Use only Circuit Protector of Shibuya’s genuine spare parts. Regarding the specification of the
Circuit Protector, refer to the spare parts list attached in the end of this manual.
CAUTION!
Make sure that core bit is not stuck before restarting from the trip of overload switch or circuit protector.
Otherwise, it may cause an injury or machine damage.
[2] CLUTCH SYSTEM
This machine has an Inner Clutch System to protect gear parts. If Core-Bit is suddenly jammed due to the presence of
piece of iron or similar materials, Spindle and gear parts are subject to severe shock. The Clutch System plays an
important role in such situations by relieving the shock. The Clutch System only operates if the gear parts are subject
to potentially damaging shock.
CAUTION!
The long time operation or operation at heavy-duty construction site would make the Clutch System
loose. If so, have it repaired by Shibuya’s authorized service center.
Do not try to tighten it by yourself.
[3] UNDER-VOLTAGE-DROPOUT
The built-in under voltage dropout in a main switch for rig fixed mode or under-voltage-dropout in the PRCD cuts off
the main power supply when voltage is dropped. The purpose of under-voltage-dropout is initially to avoid the
sudden restart after power failure, secondary to protect operator and machine from under-voltage-condition.
Under-voltage occurs under the following condition.
1) Power supply is insufficient.
2) Too long extension cable is used.
3) The size of extension cable core is insufficient.
4) Electric leakage
CAUTION!
If you failed to start the drill motor, have the condition checked by qualified electrician before sending the
machine for repair.
[4] VARIABLE SPEED CONTROL TRIGGER
At hand held operation, you can adjust the spindle speed by depressing or releasing the trigger. The drill is designed
to generate its full power when the trigger is fully pressed. When you start drilling, you can run the Core-Bit very
slowly. As the Core-Bits segments going into concrete, you can increase the spindle speed gradually. And when you
get a kickback from the jamming Core-Bit, merely releasing the trigger can reduce the machine power.
CAUTION!
At the partial trigger-position, the machine does not generate its intended power. To adjust the peripheral
speed of core bit, please select suitable gear position.

HOW TO OPERATE THIS MACHINE
7.0 HOW TO OPERATE THIS MACHINE
In this chapter, installation of this Drill Motor, and how to operate the machine are explained.
7.1 INSTALLATION OF SIDE HANDLE
To use RH1531 at hand held mode, install the included side handle to the drill nose. Turn the handle to clockwise
to make it tight. To loosen it, turn the handle to counterclockwise. Do not over tighten the side handle.
7.2 CHOOSE PROPER REVOLUTION SPEED
RH1531 has a 3-Speed Gearbox. “H” is a high-speed range, “M” is a middle speed range, and “L” is a low speed
range.
A proper speed range should be decided, based on the diameter drilled. Refer to the following tables. Note this table is
merely reference. Maximum drilling diameter depends on the hardness of concrete, aggregate, size of rebar, drilling
depth etc. However do not exceed the maximum diameter.
Model Speed
Range Hand
Held Rig
Mounted Rev. (No-Load) Drilling Diameter Recommendation
H
4150min-1 14.5mm to25mm (1/2” – 1”)
M
2000min-1 27mm to 65mm (1 1/8” – 2 3/8”)
RH1531
L
800min-1 65mm to 180 mm (2 1/2”-7”)
Before plug into power supply, shift the gear selector to choose
proper gear by turning the spindle of drill by hand.
7.3 ATTACH CORE-BIT
RH1531 has a spindle shaft of G1/2” (BSPP 1/2”) female thread. In order to use the core bit other than G1/2” male
thread, such as 5/8”-11 and 1-1/4”-7, thread adaptor may need to be installed. Refer to following sketch.
Screw in a Core-Bit and an adaptor and tighten them gently with a wrench.
DANGER!!!
Make sure machine is unplugged until all the settings are completed.
DANGER!!!
Never use Speed Range-L at hand held operation. The drill motor generates highest torque at Low gear
range, especially at the moment when core bit gets stuck. Failure to obey this instruction may result in
serious injury.
CAUTION!
Do not shift the gear while the drill motor is running. It may result in
the damage of whole transmission gear system.
TIPS!
Lubricate the thread of the Spindle with some grease and
then attach the Core-Bit. The lubricant on the thread makes
Core-Bit removal easier after drilling.
CAUTION!
The gear must be shifted when the Drill Motor completely stops its revolution. If the gear is not shifted
well, shift the gear while rotating the Spindle by hand.

2) Turn the Water Cock to supply water.
3) Hold the drill firmly and touch the drilling object gently with the core bit at slight
angle.
4) Pull the variable trigger switch a little and cut a shallow groove of approx. 3mm
(1/8”) depth.
5) Align the drill at 90 degree against the drilling object. Pull the trigger deeply to raise the spindle speed and
power.
6) Continue to apply moderate pressure, so as not to trip the overload switch.
7) While drilling pay attention to keep 90 degree against drilling object.
8) When you reach the desired depth, (or penetrate the object), pull out the drill.
9) Release the variable trigger and stop supplying water. Then disconnect from main power supply.
7.8 OPERATING PROCEDURE WITH DRILL STNAD
RH1531 is designed as a multi-purpose drill, which can be used with drill stand as
well. There are two ways to fix RH1531 to our optional stand.
One is to use with 60mm Clamp Ring Spacer shown with the illustration. In this
way, the drill motor can be installed quickly by tightening the two bolts.
The other way is to bolt it via 30mm thick bolt-on spacer to carriage. In this way,
you will have more stability when you drill with angle base or when you drill bigger
diameter core bit. And it makes the distance between spindle-center to wall
minimum. It is effective, when you want to drill small diameter hole closer to wall.
For the dimensions with TS-162 drill stand with RH1531, please refer to the
annexed drawings at the end of this handling manual.
When you use drill stand, which you purchased as complete drill machine, as
TS-162 with R1521 or TS-132 with R1511. There are several variations of the
column length. For the 1000mm column model, please add 200mm to carriage
stroke. For the 600mm column model, deduct 200mm from carriage stroke.
1) Before you install RH1531, to drill stand, you may need to change water hose
position. If so, unscrew the Hex. Socket Plug with 6mm Allen Key and disassemble
the hose with spanner and replace the position.
If you find water leakage from hose joint or Hex socket Plug, put PTFE seal tape on
it.
WARNING!!
When you penetrate the drilling object, confirm the proper protection for people and property is prepared
at down floor. (Or at the opposite side of the wall.)
DANGER!!!
Do not apply much force (to handle for feeding) at starting. Much pressure on the Core-Bit at starting may
let the segments of the Core-Bit come off, and it may cause an injury.
W
ARNING!!
If the core bit gets stuck or jammed during operation, do not try to free it by switching on/off the drill
motor. Disconnect the motor from main power supply and loosen it by a spanner. Failure to obey this
instruction may result in injury or machine damage.
12
HOW TO OPERATE THIS MACHINE
2) When using with drill stand, use the switches inside cover. Then you do not need to hold the variable trigger.
3) Open the switch cover, unscrew the screw with plus screwdriver.
